ROTARY CHURN.

SPECIFICATION forming part of Letters Patent N 0. 724,308, dated. March 31, 1903.I Application filed October 23, 1902. Serial No. 128,493. (No model.)v

To LZZ whom. it 771/041/ concern:

Be it known that I, JOHN THOMAS MARSH, a citizen of the United States, and a resident of Farmer City, in the county of-Dewitt and State of Illinois, have made certain new and useful Im provementsin Rotary Churns, of which the following is a specification. Y

My invention is an improvement in that class of rotary churns which are known as working body.

I employ a series of cream receptacles or carriers which are mounted and temporarily secured upon the arms of the spider or skeleton frame, which is adapted to be rotated by hand or power.

The several features of invention and improvement are hereinafter described with reference to the accompanying drawings and specifically indicated in the claims.

In said drawings, Figure 1 is a plan view of my churn, the cover of the box adapted to inclose the working parts being removed. Fig. 2 is avertical longitudinal section of the churn. Fig. 3 is a detail section illustrating the means for locking the rotary frame carrying the cream-receptacles. Fig. 4 is a perspective view of the spider or skeleton frame by which the cream-receptacles are supported and carried. Fig. 5 is a perspective enlarged view of one end of the cream-receptacle. Fig. 6 is a perspective View of one of the rightangular loops employed for securing the removable head or cover of the cream-receptacles.

As shown in Fig. 2, the box proper, A, is provided with a cover A', adaptedn for completely inclosing the working apparatus, save the crank of the driving-shaft. The creamreceptacles B are supported upon and secured to a rotatable spider or skeleton frame, which, as shown in Fig. 4, comprises a series of Tshaped arms radiating from a hub which is suitably keyed upon a rotatable shaft 3. The latter has its bearing in the body A of the boX and is arranged horizontally and midway between the ends of the box, as shown in Figs. 1 and 2. The radiating portions l of the spider-arms are provided with cross-heads 2 at their outer ends, which are in turn provided with outwardly-projecting flanges or lugs 4 for engaging the ends of the creamcans B, as shown in Figs. 1 and 2.

The

`receive a Screw-bolt 9.

means for securing the cream-receptacles B in place comprise two opposite semicircular straps or bands 5, which are bent at their out-er ends to form parallel portions 6. Screwbolts 7 (see Fig. 4) are adapted to pass through holes in the ends 6, and a screw-nut 8 is applied to said bolt, as shown in Fig. l.

'Ihe inner parallel ends 6 of the straps 5 are secured tothe arms l of the spider by means of a small bolt and nut. The cans or other cream-receptacles'B will in practice be of vsuch size that when the straps 5 are clamped around them, as shown in Figs. 1, 2, they will be held securely in place ou the cross-heads 2. It is obvious, however, that the screw-bolts 7 will allow considerable spread of the outer portions of the straps 5, so that cans of considerably greater size may be employed. In other words, the construction and combination of part-s are such that a considerable Variation in the size of the cans B is practicable. As shown in Figs. 2 and 4, the inner ends of the straps 5 are extended and provided with notches or open slots, which adapt them to The latter passes through the arms 1, and a nut is applied to it, as in the case of the bolt 7. By this arrangement the arms 5 are clamped in the radial positiontshown in Fig. 4) by means of the said bolts 9; but by loosening the latter the straps 5 may be .turned down upon their pivot-bolts into parallelismwith the cross-heads 2, asindicated Yby dotted lines, Fig. 2. This feature is of value in some cases when it is desired to ship the .spider or frame in compact form, also in handling and storing the same. Ordinarily, however, the apparatus will be shipped as a whole.-

As shown in Figs. l and 2, each of the cream-receptacles B is held at a right angle to a radius of the shaft 3. There is obviously no limit to the number of arms, and therefore of the number of receptacles B, which may be employed, so long as the arms I shall be extended so as to allow space for accommodation of the receptacles. The receptacles B will in practice be provided interiorly with a suitable cream-breaker. Instead of applying crank 10 directly to the shaft 3 it may heap,- plied, as shown in Fig. 1, to a short or stub shaft 3a, having a sprocket-wheel 11 on its inner end within the box A, from which a chain 12 extends to another sprocket 13, mounted on the shaft 3. By this means the spider or frame carrying the cans B may be driven at greater or less speed, as may be desired. Itis obvious that a pulley may be applied in place of the crank if it be desired to employ other than hand-power for driving.

When a receptacle B is being iilled or emptied, it is held in vertical position, and for locking the skeleton frame or spider with any one of the cans in the required position l provide a dog 14, (see Figs. 1 and 8,) which is pivot-ed at one end and provided at its free end with a tooth adapted to enter sockets in a disk 15, keyed on the shaft 3. It is obvious that the said disk will be provided With four sockets correspondingin number and arrangement to the cream-receptacles B.

It is important that the receptacles B shall be provided with covers adapted to have a tight closure and that such closure may be easily and quickly effected. For this purpose l employT a series, preferably four, of rightangular lever'arms 16 (see Figs. 5 and 6) and screvwbolt 17 and wing-nut 1S. The said arms 16 are formed of stout wire or small iron rods bent into loop form, the same being hinged on the sides of the can B and their free ends adapted to pass over the screw-bolt 17, which projects from the center of the cover b. When the arms 16 are thus arranged in due position, as shown in Fig. 5, the Wing-nut 1S is applied to the bolt 17 and screwed down. The arms 16 should be made of spring material and their shorter members should be of slightly less length than the distance between their pivotal points 19 and the outer side of the cover h, so that when the arms 16 are clamped by the nut 1S due leverage will be applied and the cover ZJ therefor held elastically but tightly in place.

There is obviously no limit to the dimensions in which the working apparatus may be constructed; but when made of small size it is particularly adapted for use by farmers or others having but a small quantity of cream, requiring to be daily or otherwise periodically churned.

The machine is easily operated and is simple in construction, so that it may he cheaply manufactured. lt is also very eflicient in operation and easily manipulated for introduction of cream and removal of butter from the several receptacles. .It will be seen that if the quantity of cream to be churned is very small a single can or receptacle B may suftice, and in such case, for the purpose of balaneing the apparatus, the opposite can B will be filled with the same quantity of water. Thus a very small or considerable quantity of cream may be churned, as conditions require.

What l claim is- 1. The combination with a horizontal rotary shaft and a skeleton frame keyed thereon and comprising radial portions adapted for supporting the cream-receptacle, of clamps for securing such receptacles, the same comprising each two semicircular bands whose ends are bent outward and perforated, and fastening devices passing through said ends and serving to secure the said bands around the receptacles, as shown and described.

2. The combination, with a rotary shaft and a skeleton frame keyed thereon and coinprising aseries of arms having right-angular cross-heads provided with end flanges or lugs projecting outward, of clamps for the creamreceptacles, the same consisting of two opposite, semicircular bands of elastic material having outturned ends and screw-bolts and nuts passing through said ends and serving to secure the bands to the cross-heads and compress them upon the receptacles substantially as shown and described.

3. The combination with a rotary shaft and radial arms duly keyed thereon of clamps for securing the cream-receptacles in place the same comprising curved bands which are pivoted to the arms and provided with lateral notches in their inner ends, and clampbolts passing through the arms and adapted to enter the said notches substantially as and for the purpose specified.

4. The combination, With the rotary transverse shaft, and the frame keyed thereon and comprising T-shaped arms whose transverse cross-heads are provided with end fianges eX- tending radially, and with means for holding cream-receptacles on and parallel to the said cross-heads and between the fianges thereof, substantially as shown and described.

5. In a churn of the character described, the skeleton frame consisting of a series of radial arms having on their outer ends transverse cross-heads, and bands secured to the cross-heads and extending outward therefrom and adapted for securing cream-receptacles in place parallel to said cross-heads, substantially as shown and described.
